INPUT SHIFT REGISTER
The input shift register is 24 bits wide and consists of a read/write bit (R/ W ), a reserved bit (zero) that must always be set to 0, three
register select bits (REG0, REG1, REG2), three DAC address bits (A2, A1, A0), and 16 data bits (data). The register data is clocked in MSB
first on the SDIN pin.
